Service is billed based on the total number of unique email addresses per list. In other words, Net Atlantic bills for every email address on each list during the billing cycle. Monthly fees are not based on the frequency of your mailings and you will be charged even if you do not send. The cost of your list can increase or decrease monthly based on its size. Please see our pricing schedule for further details.

Bandwidth is the amount of data transmitted and received on our servers. Each Professional Level mailing list receives one gigabyte (GB) of bandwidth per month. Enterprise Level mailing lists receive 2 gigabytes (GB) per month. Any bandwidth usage that exceeds the monthly allotment costs $10 per additional GB.
